Frequently Asked Questions
Is there a core charge for this aftermarket emissions unit?
No, this is a 100% brand-new aftermarket component. Unlike remanufactured and OEM factory units, there is absolutely zero core charge, zero tracking paperwork required, and no need to spend money shipping your old, dirty unit back to us.
Does this replacement unit come with the necessary clamps and gaskets?
When you select the "Full Kit" option from the dropdown on this page, heavy-duty clamps required for installation are bundled and shipped directly with the assembly. This unit is engineered to fit without gaskets. Selecting the component-only option provides the bare unit without hardware.
How fast will my order ship out?
Orders confirmed before 2:00 PM Eastern standard time ship out from our closest regional fulfillment hub on the exact same business day. Free standard ground shipping is included to the continental United States, and expedited overnight air choices can be selected directly at checkout.
How do I verify this aftermarket filter matches my truck's setup?
You can verify fitment by identifying the original casting, housing, or tag stamp directly on your factory exhaust unit canister shell. If that number matches any of the cross-references listed on this page, or if your engine model and year line up with our application guide, it will bolt directly in with a perfect factory alignment.
Disclaimer: Product images for reference only. Final replacement hardware items matching OEM parameters such as clamps and sensor ports depend on your kit configuration. Selecting the "Full Kit" option adds the explicitly listed installation components to your shipment. Price is for one (1) DPF or DOC only.
